So I built two lagoon maps in the beta which use the new blocks for lagoon that weren't in trackmania turbo (besides block variants). In my opinion they show incredible potential for tech maps in lagoon because they allow various turns and combinations. They also look beautiful (as long as you don't get too close to the windows). Sadly I can't upload them at the moment because they are broken in the final release since some of the city blocks don't connect properly anymore. http://i.imgur.com/aVOn0Xw.jpg
